Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

Last week we saw the benefits of rethinking memory and pointer models at the hardware level when it came to object storage and compression ( Zippads ). The goal of all this of course is to prevent attackers injecting, manipulating or abusing pointers in the runtime environment. For a macro-benchmark PostgreSQL’s initdb tool was used.

The challenging thing of course, is efficiently maintaining all of these parallel universes. If we do that naively though, we’re going to end up with a lot of universes to store and maintain and the storage requirements alone will be prohibitive. Expressing privacy policies. It runs to about 2,000 lines of Rust.

Please, pay attention to the difference between engines: InnoDB is a transaction engine, and MyISAM is a non-transactional storage engine. That is why it can instantly answer COUNT(*) and COUNT(val_no_null) queries. For IO-bound workloads, you frequently can see even a 100 times performance difference in this case.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Not as much as we'd like, of course, but the worldwide baseline has changed enormously. There are differences, of course, but not where it counts. The Moto G4 , for example.

Consider costs : Multiple factors will, of course, affect how much you should budget. Networking equipment (switches, routers, etc.)

Big news this week was of course the launch of Cluster GPU instances for Amazon EC2. There was an excellent first benchmarking report of the Cluster GPU Instances by the folks at Cycle Computing - " A Couple More Nails in the Coffin of the Private Compute Cluster " The Top500 supercomputer list.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. Chrome has missed several APIs for 3+ years: Storage Access API.

Budgets are scaled to a benchmark network & device. Deciding what benchmark to use for a performance budget is crucial. Simulated packet loss and variable latency, however, can make benchmarking extremely difficult and slow. Time required to read bytes from disk (it’s not zero, even on flash-based storage!).
